What term describes the gradual reduction in width or thickness along the length of an elongated object?

• A. Taper
• B. Counter Bore
• C. Half Section
• D. Detail View

Answer: (A)

A taper is the gradual reduction in width or thickness along the length of an elongated object. This means the part becomes smaller smoothly from one end to the other, creating a continuous change in cross-section rather than a sudden step. Tapers can be conical or linear, and are described by the angle or the length over which the dimension changes. This concept is used in designs to improve fits, ease assembly, or manage stress as the geometry narrows. Counterbore refers to enlarging a hole for a fastener head, a half section is a drawing method to show interior features by slicing the object in half, and a detail view is a magnified representation of a small area. None describe a gradual lengthwise change in cross-section like a taper does.
